Version 2.0 is a new major release. Users upgrading from 1.x versions should read these release notes carefully before upgrading, as many changes are not backwards compatible.
The config file specification has been reorganized, with the settings broken down into smaller sections to make it more manageable. You will not be able to reuse your old v1.x config file, but most of the settings have been carried over to the new format. You can refer to the configuration file documentation to adapt your old config file to the new format. One thing that hasn't changed is the menu specification. You can copy and paste your old menus verbatim into your new config file.
The biggest change in functionality v2.0 relates to the OnLaunch setting. Previously, Flex Launcher would track the launched application's process status to determine when the application started and finished. This turned out to be a poor indicator of whether or not the launched application was running, particularly on Windows. Flex Launcher v2.0 uses the window focus state to determine if the application is running: when the launcher loses the window focus it assumes the application has successfully launched, and when it regains the window focus it assumes that the application has finished. Consequently, the "Hide" OnLaunch mode has been removed, since it relied on the process status which is no longer considered reliable. "Blank" is now the default, with "None" still available.
